SlapJack Jr

SlapJack Jr is a single-player version of a children’s game where one player extends their hands forward, roughly at arm's length, with their palms down. The other player's hands, also roughly at arm's length, are placed, palms up, under the first player's hands. The object of the game is for the second player to flip their own hands over the opposing player’s and slap the back of their opponent's hands before they can pull them away. If the slapping player is able to hit their opponents hands, then they earn a point. If the slapping player misses, then their opponent earns a point.

Use attached CAD model to cut and assemble cardboard structure (5"x11" cardboard sheets) and popsicle stick supports. All materials can be secured using tape. Secure Arduino Uno and breadboard to base with tape. Wait to attach back piece until electronics have been assembled and wired.

Follow diagram to assemble electronics.

See images for attaching ultrasonic sensor (to popsicle arm), LED placement (secure with tape). Servo motor secured flush to front panel using included screws. Attach popsicle stick arm to the servo (with straight bar attachment) at the center using included screws. Potentiometer is placed in the breadboard on the Arduino and adjusted using flat head screwdriver. Power using 6V battery pack.
